Forensic Sciences: The Science of Fingerprint Identification

After considering many of the areas covered by forensic science, the main criteria for narrowing my choice and final decision on final ballistics and / or fingerprint analysis are based on work complexity and sharp eye needs . I tried it. It is no doubt that other areas, if not so difficult, are another important factor for making a hard decision to change such a life. The history of recognition of gun and tooling markings began with simple observation, physical matching, and caliber determination and has evolved over the past 165 years.

Modern forensic science began in the late nineteenth century when European criminal investigators began using fingerprint recognition and other identification techniques to solve crime problems. As the field of science expanded through the 20th century, its application to legal issues became more common. The list of forensic science is long, as almost all scientific disciplines can affect the law. Forensic medicine is one of the biggest and most important areas of forensics. It is also known as lawful medicine or medical law, it applies medical knowledge to criminal law and civil law. The medical fields normally involved in forensic medicine are anatomy, pathology and psychiatry. Many law enforcement agencies adopt forensic pathologists, sometimes called examiners.

In forensic science processes, forensic devices are used to process samples and evidence and are expected to solve crime problems. Measurements include evidence analysis, fingerprinting or DNA identification, analysis of drugs or chemicals, and treatment of body fluids. Importantly, the fusion of science and technology has enabled forensic scientists to do a lot of work. Science in biology, chemistry and mathematics is combined with various techniques for processing evidence. Very good equipment, Phenom SEM for shell debris makes it possible for criminal laboratories to find cannon residue. Next, this technique uses energy dispersive spectroscopy to characterize the residue to quickly distinguish between gun shot particles and dust, dirt, and other fibers. It is fully automated and is completely user-friendly as software and hardware are fully integrated.

One of the oldest techniques in forensic science is to clean fingerprints. Fingerprints are absolutely reliable identification means. In addition to the value of arresting criminals, fingerprints can also guarantee that individuals identify humanitarian causes such as amnesia, missing persons or unknown dead. Fingerprints are extremely valuable for identifying tragedies such as fire, floods, car crashes. In the case of a criminal case, in addition to identifying the identity of the arrested person, the fingerprint record provides a history record of known violators or indicates whether the person is a criminal. The vast majority of fingerprints held by the Federal Bureau of Investigation's identification (the world's largest fingerprint library) are used for civil records. In most cases, traditional fingerprint surface dust removal methods are still in use.
